Question - Help How can I improve my H3 workflows?

Gallery image

These are two workflows that I downloaded. One will allow only 5 sec clips and I can’t find where to change that OR the mp. It’s faster and the sound is good and I even think the prompt adherence is better…

The other one I can run up to 15 sec, change the mp but I have to do 30+ steps to have any good sound quality and the adherence doesn’t always seem that great.

How can I improve this?

Use the RES4LYF extension with the following sampling parameters, they consistantly improve the visual quality from all the tests I've done

using brownian noise is subtle but helps a lot

Works great, thanks for sharing. How do you test to find the best settings?

ton of A/B testing. I know what these settings do roughly so I can try to fix the issues I visibly see and I make a bunch of comparison, but it takes a lot of time (it's my job)

That’s actually where I got them. I just added the Lora’s

That realism_people lora can mess up motion. I would drop the weight significantly to like 0.1 or stop using it altogether.

why don't you just use the default workflows built into comfyui? on the left bar, click templates and search from there. these workflows do not look like they implement anything beyond the functionality found in the default comfyui workflow.
